3 Claims. (01. 268-126) My present invention relates to automobile window sash mechanisms, and more particularly to improved window sash elevating mechanism.

The principal object of my invention is an improved automobile window sash mechanism;

Another object is a parallel elevating and loWer ing mechanism for sliding window sashes;

Still another object is the combination of a counter-balanced parallel elevating and lowering mechanism for sliding window sash, and

Other objects and novel features comprising the construction and operation of my device will appear as the description of the same progresses.

In the drawing illustrating the preferred embodiment of my invention:

Fig. l is a side elevation of the apparatus removed from an automobile door;

Fig. 2 shows the opposite side of the elevating and lowering mechanism, as viewed in Fig. 1, a portion of the sash pane being broken away for convenience, and

Fig. 3 shows a cross section taken on the line 3-3 of Fig. 1.

In Fig. 1 I have indicated at Ill, in broken lines, a panel of the door of an automobile. At II I have indicated the opening of the window, also in broken lines, the window being shown in a closed position. The sash pane l2 of the window is provided with a bottom channel member I3, as is usual in window construction of this type. At two separated points on the channel member I3 I have attached, as by welding, two right-angled bracket members I4 and I5.

At I6, I have indicated a curved plate member which is bolted at I! to the panel member Ill. The entire mechanism is carried on the bolts IT.

The apparatus shown in the drawing is provided with certain locking mechanism inclosed within the casing I8 which cooperate with the lever I9 and the toothed periphery 20 on the fixed plate I6. This locking apparatus is fully disclosed in my copending application entitled Automobile window sash lock, filed September 3, 1937, Serial Number 162,283, in which the mechanism with which this application is concerned is also disclosed. This is a division of the mentioned application. For the purposes of. the present application, the fixed plate 20 may be of any shape and without the toothed periphery 20. Also the lever I9 may be considered as being attached to the bell-crank lever 2I in a permanent manner.

Through the plate I6 is journalled a shaft 22 the front end of which is slotted to receive the counterbalance spring 23 the other end of which is anchored around the pin 24 fixed in the plate I6. The other end of the shaft 22 is preferably squared on the portion which protrudes beyond the plate l6 and is fitted in a squared opening in the lever 21. A washer 25 and machine screw 26 are provided to hold the shaft collar 21 tightly against the plate I6 thereby maintaining the lever 2| and plate I6 in contact with each other.

At 28 I have provided a second bell-crank lever reversally positioned with respect to the bellcrank lever 2|. The long leg of the lever 28, as shown at 29, is slidably pivoted at 30 in the horizontal slot 3| located in the bracket I4. The bracket I5 is similarly provided with a horizontal slot 32 which is adapted to receive a pivot pin 33 which is fixed in the lever 2| and journalled through the lever 28. A top extension member 35 is located on the lever 28 and is adapted to bear against the vertical leg of the bracket I5 for the purpose of maintaining the apparatus in a braced relationship with the plate I6 thereby preventing such apparatus from becoming cramped when in operation. Below the shaft 22 and a part of the plate I6 I have provided a hanger 36. A lower arm 31 is provided on the lever 28. The connecting lever 38 is pivoted at 39 to the lever leg 31 on one end and at 40 in the hanger 36. The center distance between the shaft 22 and pivot pin 40 is equal to the distance between the pin 33 and 39 in the lever 28. Also the vertical axis taken through the centers of the pins 33 and 39 is parallel to the vertical axis of the centers of the shaft 22 and pin 40.

When the horizontal lever 45 which is pivote at 46 to the lever I9, is pulled to the right or left, the lever 2I applies force at the pin 33 and elevates or lowers the glass I2 thereby opening or closing the window, as the case may be.

With window glass which is wider in a horizontal direction than in a vertical direction it is necessary that the sash pane, as I2, be moved up and down in a perfectly vertical direction otherwise it will tilt to one side or the other and jam in the slide-ways of the door frame. In my present arrangement the parallel bar 38 maintains the horizontal leg of the lever 28 in a horizontal plane at all times and the forces exerted primarily on the pin 33 are partially transposed to the pin 30 in the bracket I4 thereby giving the glass I2 a vertical movement with equal forces applied at two separate points. An illustration of the change in position of the mechanism is shown in dot-and-dash lines in Fig. 1 showing the lowermost position of the apparatus.

Having thus descrilied my invention what I claim-as new is:

1. An improved automobile Window sash elevating'meohanism comprising in combinationfa plate fixed to the frame of said window, slotte d brackets attached to the bottom edge oii said sash, said slots being elongated in horizontal plane, an inverted L member slidablfy engaged in said slots, the long side of said L member being provided with studs adapted to engage in said slots,

I mobile door Window-sashes comprising, a belli an extension member attached tonsaid L member at a point abeve its right-angle corner, said extensien member being adapted to bear against the side of the respective bracket, a bell-craiik lever one leg of which is pivoted on the stud located at the said right-angled corner of said L member, the other end of sad bell-crank lever being connected to a horizontal hand operating leveiysaid bell-crank lever being pivoted to said fixed plate, a parallel lever pivoted'to the depending end of said L member .at one end and the opposite end being pivoted to said fixed plate. 1 2. improved automobile Window sash operating mechanism comprising, a plate fixed to the frame of said window, a bell-crank lever pivoted to said 'plate, horizontally slotted brackets attached to ithe bottom of said sash, a lever provided with studs slidably mounted in said slots, said lever having a depending extension arm at oneend, the free end of said depentf ng lever being eonnected to a parallel lever attached to said fixed plate, an extension above said depending arm adapted to bear against the adjacent slotted bracket, means for operating said bell-crank lever. I

3. Improved operating mechanism for autocraiik lever pivoted to said door horizontally slott'ed'brackets attached to said sash, a rightangled lever comprising a horizontal and vertical arm, the horizontal portionbeing slidably pinned in said slots, the vertical arm end of said rightangled lever being: pivoted to one end of said bell-crank lever, a parallel lever piY ted to one end of said vertical portion of said right-angled levier and said door, a guide member located on said right-angled lever adjacent the Vertical end portion and adapted to engage one pf said slotted brackets for the purpose of stiffening said rightang'led lever.
